Guðjón says that Icelandair has received numerous queries from passengers over the situation, though there has been no abnormal increase in passenger cancellations.
"The story is being covered worldwide. People are naturally concerned about their flight plans," Guðjón states. The Eyjafjallajökull eruption in 2010, along with its disruption of flights all across Europe, are still fresh in people's minds.
"People think this will be a similar eruption", says Guðjón. While people are expecting another Eyjafjallajökull scenario, the truth is that circumstances are completely different than four years ago.
"Among the many things that have changed is the available research data, as well as the methods employed by scientists to measure the effects of the eruption, like ash density. All of this is different than what was available during the Eyjafjallajökull eruption," Guðjón adds. "Even if an eruption of a similar magnitude were to occur now, we would be far less concerned about it than we were four years ago."
Seismologists at the Icelandic Meteorological Office (IMO) have reclassified the earthquake close to the Bardarbunga volcano last night.
Over the last seven years seismic activity has been gradually increasing in Bardarbunga and the fissure swarm north of the volcano.
Of these around 950 have occured since midnight today. Several of these events were larger than magnitude 3.
The seismic activity in Bardarbunga on the Vatnajokull glacier is very powerful and therefore full reason to expect a volcanic eruption according to a specialist at The Icelandic Meteorological Office. A live webcam has been placed in the vicinity of Bardarbunga.
